. DRYING APPARATUS.

Application filed December My invention relates to a drying apparatususeful in efi'ccting a drying of thread, yarn and the like, and particularly adapted for use for e'fiecting the drying of thread, yarn and the like after it'has gone through the glazing or dressing process.

In the manufacture of thread, yarn and the like it is customary to put it through either a glazing or a dressing process for purposes well known to the trade. The thread in passing through this glazing or dressing process becomes moistened and it is desirable that the moisture be removed to a certain degree preliminary to the winding of the thread, yarn or the like into that form in which it is sold commercially.

In the present application I have shown the invention used in connection with the manufacture of thread. The application and use of the invention however. will be the same in the manufacture of yarn, twine or other similar material, as will appear from the description set out herein.

In passing the thread through the glazing or dressing process it is-carried from a creel to a dresser which usually embodies a size box or reservoir containing the dressing or glazing material. After passing from the reservoir or size boxit is brought into contact with squeezing rolls and a series of brushes at a suitable temperature. These brushes or other cleaning and polishing and drying agents are ofvarious numbers depending upon the type of machine with which used and in the drawings I have shown a two-brush dresser The brushes serve to remove from the surface of the thread the excess dressing or glazing materialadhering thereto and also serve to lay the projecting fibers and to polish the thread and to wipe it dry so as to remove to a certain extent the moisture therefrom. From the dresser the thread goes to the take-up frame where in the case of thread it is wound upon spools.

Experience has "shown that when the thread passes above certain speeds the dresser does notremove a suflicient amount of moisture from it and that after being wound upon the spool this excess moisture which still remains in the thread is a detriment to the life and appearance of the tions.

thread, and its presence is undesirable for obvlous commerclal reasons. It has been proven' from experiencethat the center of the thread no matter how small it may be,

will under certain circumstances when passlng from the dresser contam an excesslve moisture'core even when the outside surface means which will obviate the objectionable features noted and to increase the speed of production orto avoid retarding the speed of production.

It is 'anotherobject of the present invention to provide a mechanism for changing the atmosphere surrounding the'thread so as to assist evaporation and permit the'drying of the core of the thread-tothe extent desired.

In this industry with the machines as now used it is difficult to gauge the amountof work to be produced by a machine as the machine cannot be run at the'same rate of speed regardless of the atmospheric condi- When the atmosphere is excessively humid the machine must be slowed up in order topermit a longer period of travel from the reservoir or size box to the spool upon which it is wound in order that the proper amount of evaporation may take place. Since the speed of the machine is dependent to a certain extent upon the hu midity of the atmosphere the speed at which the machine may be run may vary at different periods of the day. The speed of the machine is also on account of the, reasons mentioned dependent to a certain extent upon the temperature as well as humidity of the room in which the work isbeing carried on and at the locations where the thread is v The present lnvention has a further object the increasing of the efliciency of the present machines in the industry and the pheric conditions and the temperature in 1 which the process is carried out.

It is another object of Ithepresent invention to remove from around the thread saturated atmosphere and bring into contact with the material less humid atmosphere for the purpose of assistingevaporation.

It is another object of the invention to provide means for directing a flow ot'air effect-1n desired operation. Extending upon the thread when passing to the talceup machine.

illhere is illustrated. in Fig. 1 a dresser comprising a frame 9 upon which mounted asize box 10 and rollers 11d etween "which (the thread 11. passes. This :thread then passes over the 'roller :12 and over the brush =13,"thence under the roller 14 and over 15 over the brush 16 ;and under the roller 17 through spacing hooks and to the take-up stand upon whichare mounted a plurality of spools .18. The mechanism is of a well known type and the brushes-as well asrollers 5L1 are rotated 'inthe well known manner. The take-up for the dresser is constructed in avwell :lrnown manner and comprises a sup porting frame 19 upon which. at opposite sides is mounted the vertical reciprocating {frame having horizontally extending arms 20and21 whichproject outwardly from the diagonally extending'rail22v 1 In Fig.1. the diagonally extending rail 22 isshown at the oppositeside ofthe take up for the dresser. Connecting these rails QQzttflCl 22-.are,guide bars 23 projecting upwardly fromeach of which at-spaced inter- .vals areguide hooks QdsthiOugh which :the thread or yarn is passed "in its travel from thedresser to the spools 18.

' As shown in Fig.;1.-tlie' lowermost auxiliary header 37 is connected by a suitable nipple 33-.andthe flexible coupling 39 to the end-of the header3 l. Each of theauxiliary headers 37 positioned under the other; "uide :bars 23 is cenneetedby means of nipples 38 and 4:0 and the flexible connection to the header 34. I These guide barsmove vertically for etiecting-a distribution of the threadior yarn "which is passingthrough the guide hooks 34twonto the rotating-spools l8 and it is apparent thatsince the auxiliary-headers 37 movein unison with the guide bars 23 theseiauxiliary'headers .37 reciprocate vertically relatively to the spools 18.

Golnmunicatingavith each of the auxiliary headers-37 and projecting upwardly therefromthrough the guide-bars23 are nozzles 4E1, each of whichis provided adjacentits upper end with an opening pro ably- "taced'in the direction ofi the spools l8.

All the air carrying- ;p arts are preferably designed to give;approximately uni-form dryness ofthe threadoppositeeach opening-by the useot certain sized openings at certain locations althoughregulation could be an ranged for at the nozzles, only orntstheauxiliaryheaders. it will :be noted-from the drawingsthat thethreadtravelingto the up per layers of spools travels through the atmosphere' a greater distance than the thread traveling to the lower layer of spools so that the thread wound 2011 the upper layer of spools has'more opportunity ito dry than the thread traveling to the lower layers'of spools. The openings 42 in the nozzles lfOldllle lower layers ofspools are larger than theepenings 4l2-f0r the nozzlesdirected toward the upperilayers' of spools.

fThe-construction is such that asthethread which is passing through the guide hooks -byineans'ot' the fienible pipeor hose 35 and IOU 34 is being wound upon the spools 18 and the compressed air is forced through the headers 34 and the auxiliary headers 37 a small jet of air will be playing upon the thread wound upon thespool and if desired upon the strand of thread being wound upon the spool so that the evaporation of the moisture in the threading is assisted and hastened. It is evident that the atmosphere surrounding the spools and the thread wound thereon is continuously renewed so that the surrounding of the spools with a saturated atmosphereis prevented solong as the air issuing from the nozzles ll is not of a saturated nature. 1

With a device of this kind the advantages enumerated above are obtained and the machine under ordinary conditions is permitted to operate at a constant speed. Of.

course the temperature of the room in which the work is being done, the humidity of the atmosphere in the room still has some e'lfect upon the speed with which the machine may be operated but this can becontrolled easily by properly treating the air issuing from the nozzles 41.

It is believed obvious that instead of blowing a current of air upon the thread the action may be reversed and the nozzles used for drawing from around the spools the air so that the atmosphere surrounding the thread on the spools is being continuously changed. The preferred form however is as already described and as illustrated.

With the invention applied to a machine as shown and operated as described the gloss and polish of the material will be preserved as well as the outside drynessso that an improvement in the appearance of the material generally is I effected at the same time operating at desired speeds.

In the specification and in the claims it is understood where the word thread is used that this is synonymous with thread, yarn, twine or other suitable material with which the invention may be used. It is also'to be noted that the Words in the glazing or dressing process have been used, and in this come within the scope of the appended claims. I I
